Iphuli ye-VPN enkulu ayisiyo imikhawulo emikhulu yamaseshini

I-/22 inamakheli e-IPv4 angu-1,024, futhi le nombolo kulula ukuyidida namandla okuthwala. Ichaza ukuthi uhla lungasekela izabelo ezingaki, hhayi ukuthi isango lizokwamukela amaseshini angaki noma lizodlulisa umthamo ongakanani. Ngemuva kwansuku zonke impendulo kunezibalo ezintathu ezihlukene, futhi ziyahluleka ngezindlela ezihlukene. Ukuziqhathanisa kuyindlela yokuhlobanisa ukwenqaba nokulungile.

Iphuli, ilungelo kanye nomthwalo womsebenzi kubalwa ngamayunithi ahlukene nangabanikazi abahlukene.

Iphuli linikeza ini ngempela

Qala emikhawulweni yangempela hhayi kumasiki. I-topology yesubneti inquma ukuthi iseva inganikeza amakheli amangaki, izabelo eziqinile kanye nokubekelwa kudla okunye, futhi ikheli lenethiwekhi nelokusakaza alitholakali. I-/22 inikeza 1,024 ngokomthetho futhi okuncane ngokwenzeka, futhi lokho kwanele ukuphula izibalo abantu abazilindele. Ukuhlangana namanethiwekhi okufanele amaklayenti afinyelele kuwo kungase kuqede uhla obelubonakala lunomusa. Qinisekisa ukuthi indlela yezabelo isekela uhla oluhlongozwayo ngaphambi kokulumemezela.

Iphuli elikhulu lisusa umkhawulo owodwa ncamashi. Alithinti imikhawulo yokwamukela, ilayisense noma amandla okudlulisa umthamo, futhi ukwandisa isubneti ngaphandle kokushintsha imizila nenqubomgomo yokufinyelela kukhiqiza uhla okungekho muntu ongalufinyelela.

Ilayisense livumela ini ngempela

Ukuqhubeka ngesikhathi esifanayo okusekelwa yipulatifomu kanye nelungelo lomkhiqizo kwezinye izinombolo ezimbili, futhi ngokuvamile azifani. Amalungelo angabala abasebenzisi, amadivayisi noma amaseshini wesikhathi esifanayo, futhi lezo zilinganiso azishintsheki. Imihlahlandlela yoku-oda yabathengisi ibonisa ukuthi amamodeli ahluke kangakanani, yingakho inombolo yozakwabo kusuka kudatha yakudala akufanele idluliselwe ekusetshenzisweni okusha. Funda isivumelwano esisebenza kusevisi oyisebenzisayo ngempela.

Ilayisense elibala abasebenzisi abaqanjiwe ngeke lamukele amanye amadivayisi ngenxa nje yokuthi iphuli linendawo.

Isango lingathwala ini ngempela

Isibalo sesithathu umthwalo womsebenzi. Linganisa umthamo wokuhamba okwenziwa yilawa maseshini ndawonye: amazinga amaphakethe, ukuqhuma kokuqinisekisa, izindleko zokubethela kanye nezici zenqubomgomo ezivuliwe. Amaseshini okusebenzisana kanye nokudluliswa okukhulu kwehla ngezindlela ezihluke kakhulu kumshini ofanayo. Isango lingase libe namakheli angenalutho nokwamukelwa okunelayisense, kuyilapho umthwalo ohlosiwe udlula lokho elingakudlulisa. Ukuhlela amandla okungazinaki isethi yezici kunikeza inombolo esebenza kuphela elabhorethri lapho konke kucishiwe.

Ukwenqaba yisikhathi sokubheka lokho isango elikubhalile ngalowomzamo: umcimbi wokwabiwa, isinqumo sokwamukela noma ucingo lokuqinisekisa olumile. Lezi zintathu zidinga izilungiso ezihlukene, futhi ukuqagela ohlangothini lwekliyenti akuvamile ukukhetha okulungile.

Hlobanisa ukwenqaba ngaphambi kokushintsha noma yini

Ukuqhathanisa okuwusizo kunguphakathi kwezibalo ezintathu kanye nokuhluleka okubonwe. Uma iphuli ligcwele, landisa futhi ubuyekeze imizila nenqubomgomo ekuyichazayo. Uma ukwamukela kunqatshwa kusenamakheli asele, umkhawulo ukwenye indawo. Uma amaseshini amukelwa futhi ukusebenza kwehla, inkinga ingamandla, hhayi omunye wemikhawulo emibili.

Bhala ukuthi yisiphi isibalo esiphelile, kwenzeka nini nokuthi kwashintsha ini ngemuva kwalokho. Lowo mbhalo uvimbela uphenyo olulandelayo ukuthi luqale futhi kusukela kumasiki esubneti.

Ukwandisa iphuli ukushintsha komugqa owodwa okunokulandelwa okuyingxenye ezintathu: imizila, inqubomgomo kanye nokuhlola kabusha.
